Nondisp fx of triquetrum bone, left wrist, init for opn fx

This diagnosis code signifies a break in the triquetrum bone, one of the carpal bones in the wrist, specifically on the left side. The fracture is described as "nondisplaced," meaning the bone fragments are still in their normal anatomical alignment, and it is an "open fracture," indicating a break in the skin overlying the fracture site. This code is used for the initial treatment of such an injury.

This code is appropriate for documenting the initial medical encounter for a patient presenting with a left wrist injury confirmed by imaging to be a nondisplaced triquetrum fracture with an associated open wound. This would include scenarios like a fall onto an outstretched hand where the skin was lacerated at the fracture site. It is used when the patient is first seen for this specific injury.

• Always confirm laterality (left vs. right) and the specific carpal bone involved.
• Ensure documentation clearly specifies "nondisplaced" and "open fracture" to support this code.
• This "initial encounter" code is only used for the first time the patient is seen for this injury; subsequent encounters will require different seventh characters.
